1.1 Background
Plants perform many important functions for human health. The most common is the reliable supplier of agricultural food. Ethnobotany is a study of the use of plants by indigenous peoples, and economic botany focuses on plants grown in modern times. Plants are used medicinally and provide a number of drugs. This practice is common from ancient times to the present and serves as a staple of many drugs. Industrial products such as timber, various chemicals, and paper are some examples.
Every civilization uses herbs for healing purposes. Plants serve as the foundation for the development of modern drugs and medicines that have been used daily for centuries to treat diseases (ATEŞ & TURGAY, 2003). Since ancient times, plants have been used for a number of diseases. The majority of modern medicines are derived from plants. A Pharmacognosy study investigated toxins in plants and how they influence plant health. Herbal medicines are preferred over other types of medicines worldwide because they are readily available and inexpensive and have fewer side effects (Ekka & Dixit, 2007). The rural population of the Tribes of Madhya Pradesh, India, also has a wealth of traditional plant knowledge that is important for the treatment of various diseases (Dwivedi et al., 2008). As such, humans have little access to this information, as most of it does not exist, except for Hakeems and herbalists. Thus, ethnobotanists play a crucial role in keeping traditional knowledge written down (Rama Rao & Henry, 1996). Fresh leaves of liquorice (Mlathi) have a good taste. Diabetes is recommended and has been extensively tested in animals and used in people without side effects (Megeji et al., 2005). The term "Ethnobotany" was first used by Harshberger (1896). It is a combination of four terms, namely, people, plant, use, and communication (Hazrat et al., 2007).
In ethnobotany, individuals study how indigenous plant species are used in particular cultural and regional contexts. In contrast, ethnobotany studies how plants are used for habitat, food, medicine, hunting, and spiritual purposes. By using anthropology and ethnobotany methods, ethnobotany extends the understanding of how knowledge is transmitted (Ram et al., 2004). Ethnobotany work serves as the first research method suitable for collecting information on plant use. It has also been shown that preexisting medical information provided to the general public is a source of information used in scientific research and in many plants that are fully utilized in a particular culture when found under scientific experimentation and found to be beneficial industries, so science and culture have strong links between them (Lentini, 2000).
1.2 Importance of Medicinal Plants:
A variety of herbal remedies are used to improve infertility in both males and females to solve the problems that occur in the human race (Jaradat et al., 2019). Most allopathic medicines are extracted from medicinal plants (Rashid & Arshad, 2002). The characteristics of various plant species with ethno-medicinal properties were systematically recorded, and information on the use of invasive plants was collected (Shinwari, 1996).
1.3 Ethnobotany in Pakistan
A large number of threats to Pakistan's medicinal plants are related to ignorance of the local communities and local authorities that cultivate these plants. Language barriers prevent local people from being aware of any activity designed to preserve medicinal plants. The local population is unaware of any threats to medicinal plants or of any recommendations given to authorities and experts. Another threat to medicinal plants is the overuse of firewood, careless uprooting, and consumption of food(Qureshi & Ahmad, 1996). The local communities of various parts of Pakistan have years of experience with the traditional use of plants that occur in their regions. Generation after generation has passed down this tradition of handling traditional plants. From head to toe and from cut to bruise, these herbs are used to treat almost anything (Bhardwaj & Gakhar, 2005). Pakistan is a rich natural environment where plants have been used for centuries as traditional medicines for human and animal health (Ismail & Nisar, 2010).
Pakistan has a wide variety of medicinal plants used by local communities. It is important to use these plants properly in the community at the levels at which they are used (Bibi et al., 2008). Pakistan is blessed with a variety of wild plants used for medicinal and aromatic purposes. The features and proper use of some of these plants are well known in the community and at the level of end-users; many still need to be evaluated for their therapeutic value (Shinwari & Khan, 2000). There is a semiactive ethnomedicine field in Pakistan. It has more than 5700 species of medicinal plants. There are approximately 372 plant species. Approximately 456 medicinal plants are estimated to be traded on the market for noncommercial purposes, and they are used to produce more than 350 formulas to treat a variety of ailments (Husain et al., 2003). Ethnobotany, which studies the relationship between humans and plants, was recently introduced in Pakistan. Numerous plants are used throughout the country, especially in hilly regions, for a variety of purposes. Over 6000 flowering plants grow in Pakistan, 2000 of which are used medicinally (Sher et al., 2011).
1.4 Study Area
The study area falls into the Bahawalnagar District located in Punjab, Pakistan. It is on the border. Before the independence of Pakistan, Bahawalnagar was part of Bahawalpur state under the Nawab of Bahawalpur. The city of Bahawalnagar is the regional capital. The Bahawalnagar border to the east and south affects the Indian subcontinent. Most people depend on agriculture. The local people of this region are largely dependent on seasonal plant sources and plants for their domestic needs. Most local residents are illiterate. For generations, local plants have long been used for food, shelter, furniture, medicine, etc., by different people with different lifestyles, beliefs, cultures, and cultural values. Natural resources and the environment are produced, used, and managed by them with credible indigenous knowledge systems.
1.4.1 Location
Bahawalnagar has an area of approximately 8878 km2, lying between 73°23'26.99"E (longitude) and 30°33'2.99"N (latitude). Bahawalnagar has a height of 163 m (535 ft). The Bahawalnagar region has five tehsils, Bahawalnagar, Haroon Abad, Chistian Sharif, Fort Abbas, and Minchin Abad. The Bahawalnagar borders east and south affect the Indian subcontinent, while the Bahawalpur region lies to the west, and the Sutlej River flows on its northern side (Fig. 1.4.1).
1.4.2 Climate
In summer, the weather in Bahawalnagar is very hot and dry, reaching temperatures greater than 50 °C. During the winter, the climate is cold and dry. Temperatures as low as 11 °C were recorded. Storms and wind are rare during summer, with an average wind speed of 3 km/h and 38% humidity.
1.4.3 Rivers
To the north of Bahawalnagar, the Sutlej River flows from east to west. Various canals were built from the Sulemanki Head to supply water to the Bahawalnagar tips.
1.4.4 Flora
Mulberry, guava, pomegranate, banana, orange, lemon, potato, yam, turnip, pumpkin, radish, cucumber, mint, fennel, spinach, cabbage, etc., grow there.
1.4.5 Crops
Crops are one of the main sources of food in the study area. These are the most important crops. The main cultivated crops of Bahawalnagar are wheat, barley, rice, maize, cotton, Brassica, tobacco, sugarcane, sugar beet, onion, garlic, coriander, tomato and potato.
1.4.6 Objectives
⮚ First, a few medicinal plants were identified to ensure their overall development in a particular region since the performance of plants differs in different regions.
⮚ The area was studied with reference to the ethnic uses of flora through the people of the area.
1.4.7 Localities in Bahawalnagar
● Bahawalnagar (Tehsil)
● Haroon Abad (Tehsil)
● Fort Abbas (Tehsil)
● Chishtian (Tehsil)
● Minchin Abad (Tehsil)
● Hakra (Canal)
● Cholistan (some parts located in Tehsil Fort Abbas and others in the Bahawalpur district)

1.4.8 Threats
The use of rain-fed land for agriculture is detrimental to the medicinal flora of Bahawalnagar. Additionally, wood cutting, fodder collection, and grazing are some of the major threats to Bahawalnagar from its surrounding communities. Changing climates even affect the rainy season, particularly Bahawalnagar's desert flora.
